Two-person cockpit rules and improved psychiatric screening reduce but cannot eliminate the risk. Mental health stigma in aviation remains a challenge. Cockpit door override systems have been discussed but not yet standardized.
Summary
Germanwings co-pilot Andreas Lubitz deliberately crashed an Airbus A320 into the French Alps, killing all 150 aboard. He had concealed a psychiatric diagnosis from his employer. The captain was locked out of the cockpit during the deliberate descent. The crash triggered immediate mandates for two-person cockpit occupancy across Europe and a comprehensive review of pilot mental health screening globally.
